Design of AGC and primary frequency regulation monitoring and management system

In order to meet the quality requirement of primary frequency regulation and AGC (Automatic Generation Control) for power plants in China Southern Power Grid “two rules”, the paper designs a AGC and primary frequency regulation monitoring and management system for power plant by analyzing the system requirements and combining with the actual situation of the power plant. Based on data acquisition and processing module and real-time database, the system has realized many functions such as automatic collecting, calculating and dealing with the data of the AGC and primary frequency regulation, giving a warning and analyzing the reason when the AGC and primary frequency regulation service are disqualification. After a period of trial running, it shows that the monitoring and management system can improve the quality of the AGC and primary frequency regulation services provided by the power plant. At the same time, the system can also provide guarantee for the safety, stability and economy of the generators.
